This is the classic McDonald's in the strip, I believe the drive through is open 24 hours a day.
The service is always extremely quick, and courteous, I come here on my lunch breaks a bit, and it's crucial to have such a quick option around, as the strip can get really busy, especially towards the end of the week. If you find yourself in the strip and you're looking for a quick bite at a reasonable price, this is your spot.
